Cocaine is the second most-used illicit drug world-wide and its consumption increasing significantly, especially in western Europe. Until now, annual prevalence has been estimated indirectly by means of interviews. A recently introduced direct nation-wide approach based on measurements major urinary excreted metabolite cocaine, benzoylecgonine, wastewater proposed.Wastewater samples from 41 treatment plants (WWTPs) Belgium, covering approximately 3,700,000 residents, were collected. Each...
Summary Lake sediments are globally important carbon sinks. Although the fate of organic in lake depends significantly on microorganisms, only few studies have investigated controls sedimentary microbial communities. Here we investigate impact anthropogenic eutrophication, which affects redox chemistry and matter (OM) sources sediments, communities across five lakes central Switzerland. Lipid biomarkers distributions respiration reactions indicate strong increases aquatic OM contributions...
ABSTRACT Beach ridges are depositional landforms that provide information related to coastal evolution, storm activity and sea‐level variations. However, beach sometimes modified by aeolian processes, washover and/or human activity. Therefore, systematic investigations required use as an archive of palaeoenvironmental conditions changes. In this study, a multidisciplinary approach involving ground‐penetrating radar, sedimentological analysis optically stimulated luminescence well radiocarbon...
<b><i>Background/Aims:</i></b> Heroin-assisted treatment (HAT) can improve the condition of heroin addicts still using street after a methadone treatment. In Belgium, new trial compared efficacy HAT to existing maintenance <b><i>Methods:</i></b> this randomised controlled trial, was limited 12 months. Participants were assessed every 3 They responders if they showed improvement on level use, health or criminal involvement....
Land cover transformations have accompanied the rise and fall of civilizations for thousands years, exerting strong influence on surrounding environment. Soil erosion associated outwash nutrients are a main cause eutrophication aquatic ecosystems. Despite great challenges water protection in face climate change, large uncertainties remain concerning timescales recovery ecosystems impacted by hypoxia. This study seeks to address this issue investigating sedimentary record Lake Murten...
Abstract. Even though human-induced eutrophication has severely impacted temperate lake ecosystems over the last centuries, effects on total organic carbon (TOC) burial and mineralization are not well understood. We study these based sedimentary records from 180 years in five Swiss lakes that differ trophic state. compare changes TOC content modeled accumulation rates through time to historical data algae blooms, water column anoxia, wastewater treatment, artificial ventilation, phosphorus...
Strong earthquakes at active ocean margins can remobilize vast amounts of surficial slope sediments and dynamically strengthen the margin sequences. Current process understanding is obtained from resulting event deposits low-resolution shear strength data, respectively. Here we directly target a site offshore Japan where both processes are expected to initiate, that is, uppermost part (15 cm) sedimentary sequence. Based on novel application short-lived radionuclide identified, dated,...
Significant uncertainties persist in the reconstruction of past sea surface temperatures eastern equatorial Pacific, especially regarding amplitude glacial cooling and details post‐glacial warming. Here we present first regional calibration alkenone unsaturation sediments versus mean annual (maSST). Based on 81 new 48 previously published data points, it is shown that open ocean samples conform to established global regressions U 37 K′ maSST there no systematic bias from seasonality...
Abstract Hydrogen isotope ratios of sedimentary leaf waxes (δ 2 H Wax values) are increasingly used to reconstruct past hydroclimate. Here, we add δ values from 19 lakes and four swamps on 15 tropical Pacific islands an updated global compilation published data surface sediments soils. Globally, there is a strong positive linear correlation between mean annual precipitation P the n ‐C 29 ‐alkane ( R = 0.74, 665) 28 ‐acid 242). Tropical fall within predicted range based calibration, largest...
We present new alkenone‐based sea surface temperature (SST) estimates from the eastern equatorial Pacific (EEP) for last 30 kyr. By combining these results with recently published records region, we reconstruct spatial pattern of changes in SST during Last Glacial Maximum (LGM). Alkenone‐based show a greater glacial cooling upwelling environment cold tongue than sites located further north front and Warm Pool. This result agrees paradigm stronger winds, increased upwelling, steeper zonal...
